[gem5-users] Nehalem on gem5

[Alberto Martinez via gem5-users]

Hello,
I am trying to use a Nehalem configuration that I found in this email list
right here:

http://comments.gmane.org/gmane.comp.emulators.m5.users/14015

But I am having some erros.
I moved to config/alberto the files included in the .tar that you can see
in the link I wrote (Nehalem.py, Nahalem.cfg y se2.py). And I run:

./build/X86_FS/gem5.opt configs/alberto/se2.py
--cfg=configs/alberto/nehalem.cfg
--cmd=./tests/test-progs/hello/bin/alpha/linux/hello

I found 2 errors complaining about 2 attributes in the BranchPredictor, and
I deleted them (cause there were not important for what I need to do), but
I still have some erros I cannot solve.

First I have:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/home/amartinez/gem5/src/python/m5/main.py", line 387, in main
    exec filecode in scope
  File "configs/alberto/se2.py", line 96, in <module>
    detailed_cpu = Nehalem(cpu_id = 0, switched_out=detailed_switched_out,
**cpu_options)
  File "/home/amartinez/gem5/src/python/m5/SimObject.py", line 672, in
__init__
    setattr(self, key, val)
  File "/home/amartinez/gem5/src/python/m5/SimObject.py", line 767, in
__setattr__
    % (self.__class__.__name__, attr)
AttributeError: Class Nehalem has no parameter clock


But "clock" attribute is defined in Nehalem.cfg like that:

[cpu]
type = nehalem
clock = 2GHz

I tried deleting it from there, and adding it in Nehalem.py like:

class Nehalem(DerivO3CPU):
    clock = 2
    LQEntries = 48
    SQEntries = 32
    LSQDepCheckShift = 0
    LFSTSize = 1024
    SSITSize = 1024
    decodeToFetchDelay = 1
    renameToFetchDelay = 1
....

But then I got this error:


  File "<string>", line 1, in <module>
  File "/home/amartinez/gem5/src/python/m5/main.py", line 387, in main
    exec filecode in scope
  File "configs/alberto/se2.py", line 7, in <module>
    from Nehalem import *
  File "configs/alberto/Nehalem.py", line 78, in <module>
    class Nehalem(DerivO3CPU):
  File "/home/amartinez/gem5/src/python/m5/SimObject.py", line 254, in
__init__
    setattr(cls, key, val)
  File "/home/amartinez/gem5/src/python/m5/SimObject.py", line 348, in
__setattr__
    "Class %s has no parameter \'%s\'" % (cls.__name__, attr)
AttributeError: Class Nehalem has no parameter 'clock'


Actually complaining because I added that parameter. What am I doing wrong?
Am I using this script and configuration wrong? How should I use it then?

Thanks a lot for your attention,
Alberto
